Unfortunately, my qemu command line wizard capabilities are somewhat lacking.
I had tried that before, but just could not figure out how to change my command
line to include "disable-modern=on". If you have an idea, please let me know.
Here it is:
${QEMU} -M ${mach} -cpu "${cpu}" -m 512 \
-drive file=${rootfs},if=virtio \
-net nic,model=virtio \
-kernel arch/sparc/boot/image -no-reboot \
-append "root=/dev/vda init=/sbin/init.sh console=ttyS0" \
-nographic
Thanks,
Guenter
